A friend gave me a set of hackle guards that were given to him a long time ago but he never used. They consist of three cone shaped disks with a short handle that has a small hook on the end of the handle stem and one small weight that has a hole through it. I know how to use hackle guards but seldom do preferring to use a short section of drinking straw. HOWEVER, I am confounded as to what the purpose of the small weight is. I can not for the life of me figure out what the heck it is for. Can anyone tell me?
